KNUTE L. LODVEE, OF CHICAGO, ILLINOIS.

WINDOW.

Application led January 13, 1914.

To all whom it may concern.'

Be it known that I, KNUTE L. LoDvEE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Windows, of which the following is a specification.

This invention relates to windows having sliding sashes, and the object is to provide a novel and improved means for mounting the sashes, whereby they are made removable from the window frame, thus rendering both sides of the sashes accessible for cleaning, and also obtaining better' ventilation without causing draft.

The invention also has for its object to provide simple and eiicient means for obtaining a weather-tight joint along the side edges of the sashes, the means which hold the sashes in sliding position being constructed and arranged to effectually exclude rain and drafts, and being also readily adjustable to permit the sashes to be swung out of the window frame.

The herein stated objects are attained by means of a combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawings, in order that a better understanding of the structure may be had.

In the drawings, Figure 1 is an elevation of the window; Figs. 2 and 3 are sections on the lines 2--2 and 3 3, respectively, of Fig. 1; Fig. 4 is a perspective view of one end of a sash, and Fig. 5 is an edge view of the sash.

In the drawings 10 and 11 denote the upper and lower sashes of the window, said sashes being slidably mounted between the jambs 12 of the window frame 13. The sashes do not slide in grooves in the jambs as usual, other retaining means, to be presently described, being provided. To the vertical edges of the sashes are pivoted, midway between the top and bottom thereof, rigid metal strips 14 to the top ends of which strips the sash-cords 15 are made fast. The pivotal connection between the edge strips and the sashes is made by pins 16.

Against each side of the stiles of the sash 11 are placed strips 17 having oblique slots 18 in which seat headed studs 19 carried by and projecting from the stiles. These studs hold the strips against the sides of the stiles. The slots of the respective strips are parallel and they slant in such a direction as to force Specification of Letters Patent.

the strips outward beyond the edges of the stiles when the strips are pushed upward, and inward when pushed downward. In the jambs 12 are parallel slideways or grooves 21 in which the projecting portions of the strips are adapted slidably to seat. The

.members of each pair of strips, at the respective end of the sash, are connected at the bottom by a cross bail 22, whereby they are made to move together. The top of the sill 23 has transverse grooves 24 at its ends in which the bails seat when the sash is down. Upon lowering the sash the bails first strike the sill, whereby the strips are forced outward into the grooves 21.

Retaining strips 25, similar to the strips 17 are provided for the upper sash 10, said strips 25 also running in grooves 2G in the jambs 12. As the inner strips 25 of the upper sash 10 and the outer strips 17 of the lower sash would touch, if one groove were provided for both of said strips, a separating bead 27 is mounted in the groove and the strips are located on opposite sides of said bead. The bead is tapered, and the edges of the strips are beveled to correspond. The jambs 12 have the usual groove 28 for the purpose of affording a runway for the sashcords 15. The strips 14 extend throughout the entire length of the sashes, and when the retaining strips are advanced into the grooves in the jambs 12, the sashes may be slid up and down in the same manner as ordinary sliding sashes. The retaining strips make a weather-proof joint, and e'ectually exclude rain and drafts.

When the sash 11 is to be swung out of the window frame, as shown by dotted lines in Fig. 3, it is pulled up slightly to loosen the strips 17, which latter may now, by reason of the Obliquity of the slots 18, be withdrawn from the jamb grooves by a down ward pull. The sash is now free of the window frame and may be swung out of the same to any desired position. The upper sash 10 may also be swung out of the window frame upon retracting the retaining strips 25. Suitable stops to limit the outward swing of the sashes may be provided.

The opposite portions of the meeting rails of the sashes are cut away at the ends, as indicated at 29, to accommodate the strips 17. The wall of the recess of the meeting rail of the lower sash is beveled, as indicated at 30, and is engageable by the top of the strip, said bevel serving to move the strip into the slideways and for retraeting the same, and pivoted cross bails connecting the lower ends of the strips, and adapted to seat in the grooves of the sill when the sash is l down.

In testimony whereof I aHiX my signature in presence of two witnesses.
